Subject: [PATCH 01/15] xfs: wire up Q_XGETNEXTQUOTA / get_nextdqblk
Date: Wed, 17 Feb 2016 18:20:38 +1100	[thread overview]
Message-ID: <1455693652-3899-2-git-send-email-david@fromorbit.com> (raw)
In-Reply-To: <1455693652-3899-1-git-send-email-david@fromorbit.com>

From: Eric Sandeen <sandeen@sandeen.net>

Source kernel commit 296c24e26ee3af2dbfecb482e6bc9560bd34c455

Add code to allow the Q_XGETNEXTQUOTA quotactl to quickly find
all active quotas by examining the quota inode, and skipping
over unallocated or uninitialized regions.

Userspace can then use this interface rather than i.e. a
getpwent() loop when asked to report all active quotas.
